Why are there duplicate projects and timesheets synced to Zoho Books?

Duplicate projects and timesheets may appear in Zoho Books if you have integrated Zoho Books with both Zoho Projects and Zoho People.

To resolve this issue, it is recommended that you choose one application for integration with Zoho Books. For instance, you can integrate Zoho People with Zoho Projects, and then integrate Zoho Projects with Zoho Books. This sequential integration ensures that data flows from Zoho People to Zoho Projects, and then from Zoho Projects to Zoho Books, preventing the creation of duplicate entries and ensuring data accuracy.
